Waves are all around us - from the light that allows us to see, to the sounds we hear every day. Understanding waves helps students make sense of many everyday phenomena and builds a foundation for future learning in physics, communication technologies, and more.
By the end of Grade Four, the learner will be expected to:
Assessment strategies that provide information about learning:
The Waves strand in Grade 4 helps students understand that light and sound are forms of energy that travel as waves. Light waves can be reflected, refracted, and absorbed, allowing us to see objects when light bounces off them and enters our eyes. Sound waves are created by vibrations that travel through matter, with pitch related to frequency and volume related to amplitude. These foundational concepts prepare students for more advanced study of wave phenomena in later grades.
